Fiber Optic True Time-Delay Array Antenna Feed System.
Abstract
The fiber-optic true time-delay array antenna feed is a device for dynamically generating a plurality of identical electromagnetic radiation (EMR) signals with continuously variable time-delay separations. The EMR signal to be transmitted modulates a continuous-wave optical signal from a laser source which is applied to a plurality of high dispersion single-mode optical fibers acting as synchronized true time-delay modulators forming an array antennas feed system. Each fiber is chosen to have the same nominal time delay but a different net dispersion. Photodetectors convert the otpical intensity back into an EMR electrical signal to feed each of the elements of the array antenna.
